      Liftgate Delivery


      If you ordered a liftgate delivery:

      The driver will take your skid to the back of the truck, place it on the liftgate, lower it to the ground and place it next to the truck.

      • Use the plastic shipping tarp to cover and protect your pieces until you are ready to start your project. When finished using it for this…repurpose it!
      • If liftgated down, take a minute or two to cut the straps and pull off the tarp. Check for corner damages, wood chips, sharp cuts and gauges in the product and if the pallet is broken.

        Hand Offload Only:


        If you did NOT order Liftgate Delivery, you will have to hand offload:

        The driver will take your skid to the back of the truck, cut the straps and hand the pieces down to you.  Most individual pieces weigh no more than 30-50 lbs.

        • There is a time limit of 15-20 free minutes so it is best to have someone there to assist you.
        • If hand offloading, briefly check all the pieces as they are handed to you.

          • Greetings, I am interested in the 8ft by 12ft green house. I am wondering if your business is able to accept a check rather than an online purchase. Also I am wondering how difficult assembly is, and how many people are recommended for putting it together. I am also wondering how tall it is. I will be purchasing the greenhouse for the purposes of growing some riparian restoration plants, and wanting to know how tall of willow cuttings it could support. Thank you for your time.

            Yes we can except a check or direct debit, It is recommended for one person and a helper io take 2-3 days for assembly . The height is 76- 93 inches inside. please let me know if you have any other questions.
